Chemical fingerprinting and similarity analysis of Lonicera japonica resources / 中国中药杂志

ABSTRACT

LC-MS was used to detect 41 population of Lonicera japonica from different areas. LC-MS chemical chromatographic profile has been established. There were 23 common peaks, seventeen of which were identified according to reference standard and reference; SPSS software was applied to calculate the similarity of chemical fingerprints of 41 batches and the range was from 0.99 to 0.12. On this basis, the L. japonica's metabolites consistency was classified. Combined with comprehensive analysis of genetic identity, we can provide a theoretical basis for the authenticity research of Dao-di herbs and reference information for the breeding of excellent L. japonica.
